Hard failures aside, I assume very slow charge decay might be somewhat mitigated by periodically copying files flash-to-same-flash (let alone another) -- or perhaps even rewriting them in place.
- willis936 5y agoHonestly the best answer is to this question is one that requires more effort than "burn once, sit on shelf". The best answer is "host a NAS that you actively maintain and has an offsite mirror". I personally host an all-flash NAS for the performance and MTTF benefits over HDD. Since it's always on and performs regular scrubs there is no concern of bit-rot. The data I put there will be there as long as I'm around to take care of the box and pay the B2 bill.
- daviddever23box 5y agoThis is ultimately the best option - checksummed in-flight data has a higher likelihood of being verified at both read-source and write-drain endpoints. That said - I'm at a loss to understand what software is ultimately worth using without modification after 30y....

- RonaldOlzheim 4y ago(I wrote a video game for my child’s birthday. Does that count?) For your child 100% so if that´s the goal why not? Modification is a big word. Old cars can still be valueble in capital and make you feel much more alive then a brand new car.
